MOTOR-TRACTOR FOR AGRICULTURAL PURPOSES.

SPECIFICATION forming part of Letters Patent No. 724,531, dated April 7,1903. Application filed September 12, 1902. Serial No. 123,135. (Nomodel.)

To all whom, it may concern.-

Be it known that I, DANIEL ALBONE, a subject of the King of GreatBritain,residing at the Ivel Works, Biggleswade, in the county ofBedford, England, have invented a new and useful Improvement inMotor-Tractors for Agricultural Purposes, (for which I have applied forLetters Patentin the United Kingdom of Great Britain and Ireland,numbered 3,920 and hearing date the 15th of February, 1902,) of whichthe following is a full and com-v plete specification.

The present invention relates to a mechanical tractor for agriculturalpurposes which is also applicable for use as a portable motor; and itconsists of the particular combination of parts and mechanismsillustrated in the accompanying drawings, in which- Figure 1 is a viewin side elevation of the' tractor, and Fig. 2 is a view in plan thereof.

Throughout both views similar parts are denoted by like letters ofreference.

On the rear of a frame A, carried in suitable bearings thereon, is apair of driving-wheels B, mounted on a balance-geared axle b, and at theforward end of said frame is carried a steering-wheel O, on the stem 0of which is mounted a fixed sprocket-wheel c, geared to a secondsprocket-wheel d, fixed onto a steering-pillar D, mounted on the rear ofthe frame, by means of a chain 0 On one side of the rear end of theframe, in close proximity to the steering-pillar D, is carried aseat-pillar e, provided with a seat E for the driver. At or about thecenter of the frame and on one side thereof is mounted aninternal-combustion engine F of any suitable type, the main shaft f ofwhich is arranged transversely in suitable bearings carried on theframe. Loosely mounted on this shaft f are gear-wheels f g, either ofwhich may be clutched to the shaft by means of a clutch H, preferably ofthe friction type, operated from a lever I, positioned near the seat E,by suitable connecting mechanism The gear wheel f is preferably asprocket-wheel gearing, by means of a chain f with a sprocket-Wheel lo,fixed on a transversely-arranged counter-shaft K, carried by the frame.The gear-wheel gis a spur-pinion gearing with a fixed spur-wheel k onthe shaft K. It will thus be seen that if the clutch H is so operated asto cause the gear-wheel f to be clutched to the motor-shaft f thecounter-shaft K will rotate in one direction, preferably, for theforward movement of the tractor, whereas .if the spur-wheel k isclutched to the shaft f the counter-shaft K will rotate in the reversedirection, thus providing for backward movement of the tractor, it beingunderstood that the engine F will run free when the clutch is in such aposition that neither of the gear-wheels f g are clutched to theirshaft. The counter-shaft K is geared with the axle b by means of asprocket-wheel k on the shaft 70, chain it and sprocketwheel I), carriedby the box or casing of the balance-gear b of the axle b. The whole ofthe gearing is so arranged as to impart a uniform speed of about fivemiles per hour to the tractor when the motor is running at its criticalspeed. When it is desired to use the tractor as a stationary motor, theshaft b is disconnected from the counter-shaft K, preferably byunlinking the chain and the power taken off from a pulley k mounted onthe shaft K for the purpose. The frame also carries a storage-tank L forthe liquid hydrocarbon employed, a carbureter M of any suitable type forcarbureting the air, and a water-storage tank N, containing water forcooling the motor.

The traction-bar. O, which forms the connecting medium between thetractor and the agricultural implement to be drawn, consists of a forkedbar 0, attached by its prongs to the pole at of the implement to bedrawn by means of side plates 0' and screws and bolts 0 A rod P,threaded at its one end to receive a out p, is located within the freeor opposite end of the bar 0 and passes out through a hole in the crownthereof. A helical spring 19 encircles the rod, abutting against thecrown of the bar 0 at its one end and against the face of the nut 19, sothat its strength may be varied by the said nut. A stop 0 is provided tolimit the movement of the rod in the other direction. The free end ofthe rod P is furnished with an eye 10, which is attached, by means of alinchpin 1', to a bracket R to the back member a of the frame A. It isessential that the point of attachment of the bar 0 to the member a ofthe frame A can be varied to suit the type of machine to be drawn. Inthe case of mowing and reaping machines and also with plows the tractormust be on one side--sometimes on the right and sometimes on the left.In others-such as seed-drills, scuflies, wagons, &c.it may pull quitecentrally. It is therefore necessary to provide two or more bracket-s R,as shown, or a single bracket may be used capable of being adjustablyfixed on the said member a.

What I claim, and desire to secure by Letters Patent, is-

In a traction-engine, the combination, with a frame, road-Wheelssupporting the frame and provided with a balance-geared axle, and asprocket driving-wheel b mounted on said axle at the middle part of thesaid frame; of a counter-shaft journaled in the said frame, a spur-wheel7a, a sprocket-wheel 7c, and a sprocket-pinion 10 all secured side byside on the said counter-shaft, a drive-chain passing over the wheel I)and pinion W, a motor-shaft journaled in the said frame, a motorarranged at one end of the motor-shaft toward one side of the saidframe, a spur-pinion g loose on the said motor-shaft and gearing intothe wheel 70, a sprocket-pinion f loose on the said motor-shaft, adrive-chain passing over the pinion f and wheel is, and a slidableclutch revolving with the motor-shaft between the pinions 9 and f andengaging with them alternately, substantially as described and shown.
